T all tohom it may concern I Beiteknown that I, Jon E. BARRY; a citizen of the United States, residing at Gran ville, in the county of McHenry and State of North 'D'akota, have invented certain new and useful Improvements in an Automobile-Spring of which the following is a specification."

This invention relates to automobile springs and more particularly'toia device for resiliently supporting an automobile from the axle in an improved and eflicient manner. 1 Y v One-of the objects of the invention is to provide an improved' au'tomobile spring which will utilize a plurality of telescoping cylinders operating in conjunction with superposed coil springs whereby the shock and jars occasioned by unevenness in the roadway will be absorbed by the springs.

Other objects of the invention will appear. upon consideration of the following detail description and accompanying drawing, wherein Figure 1 is a front elevation of an automobile showing the invention applied, and

Fig. 2 is a vertical section through one of the springs constituting the invention.

Referring to the drawing by numerals the base flange 1 is provided with a vertically disposed stationary cylinder '2 which may be of any preferred le'ngth and which has its top closed by the upper wall 3. This wall is provided with a stuffing box 4 through. which a piston rod 5extends and the upper end of the piston rod is secured as indicated at 6 to the top end wall 7 of an outside movable cylinder 8, which emder 10, which is substantially half the length of the stationary cylinder 2 and has a sliding fit thereon. The lower end of the coacting cylinder 10 is closed by the lower end wall 11 and a coil spring 12 is interposed between the wallll and the bottom of the stationary cylinder 2.' Arranged within the co-acting cylinder 10 is another movable cylinder termed the equalizing cylat emam e;

inder! 13 -which" is somewhat shorter. in

length. than the A co-acting ycylinder'. 10 as shown in the drawings. The'upper ends of each oftheflcylinders -10'and 13 are open. i

end Wall 11 of the coacting cylinder 1O. Another coil springl'6 is interposed between.

the piston'1-4 and thGl'CiOSGduIld of the equalizing cylinder 13 while a shock absorb ing spring 17 is interposed between theend wall 30f the stationary-cylinder and the top of the piston 14. I A quantity of oil is contained. in the lower end of the stationary cylinder 2 as indicated by the space 18 andthe closed end wall of theoo-acting. cylinder 10 .and the equalizing cylinder 13 are provided with oil openings 19 and 20 whereby oil may be passed into the cylinders from the lower end of the stationary cylinder 2 when the de-. vice is in operation. t'

It will beapparent from the above description that the cylinders have sliding contact with each other and the springs arranged in superposed relation are adapted to cooperate so that all shocks and jars will be entirely -eliminated' whe'n the apparatus is employed to support the vehicle from the axle of the automobile. .The base flanges 1 are mounted upon the axles as shown to advantage in Fig. 1 and it will be obvious that four of the devices will be employed, two being mounted on the front axle and two being mounted on the rear axle so that the automobile body will be supported by the springs at the four corners of the body.

Minor changes may be made in the details of construction without departing from the spirit of the invention or the scope of the' carried by the said outside cylinder and extending into the innermost sliding cylinder, and coil springs engageable with the said piston and With the ends of the said cylinders.

2. A device of the character described comprising a plurality of telescoping cylinders including a stationary cylinder, an out side sliding cylinder embracing the stationary cylinder, at supporting rod carried by the sliding cylinder, a piston suspended from the closed end of the sliding cylinder, the said piston being extended into the interior of the said telescoping cylinders, and coil springs arranged on the interior of the said cylinders.

An automobile spring comprising a stationary cylinder, an outside sliding cylinder vembiicing the stationary cylinder, and

equipped with a supporting her, episton rod secured to the top of the sliding cylin der and provided with a piston, a co-acting cylinder arranged Within the stationary cylinder, en equalizing cylinder arranged within the co-acting cylinder, and coil springs interposed between the ends of the cylinders and other springs engageeble with the opposite sides of the said piston. v

4. An automobile spring comprising a stationary cylindennn outside sliding cylinder embracing the stationary cylinder, and

equipped with a supporting bar, a piston rod secured to the top of the sliding cylinder and provided'with a, piston, e coecting- I cylinder arranged Within the co acting'cylinder, i an equnligingzcylinder arranged with- In the 'co-ectlng cylinder, and coil *sprll'lgs interposed betweenthe ends of the cylinders and other springs engegeeble With the opposite sldes of the sa d piston,,the lower end o: the stationery cylinder being provided Wlth an oil space adapted to contain a quantity of oil the closed ends of the inner cylin-- i
